摘要： A program cartridge 4 is detachably attached to a body device 2. The game cartridge 4 stores a game program and certain data. The body device 2 reads the game program from the game cartridge 4 and executes the game program, and reads the certain data and refers to the data to display OBJ images and BG images provided with parallax in left and right display systems. That is to say, the body device 2 displays in the left and right display systems planar OBJ images having no parallax themselves shifted in the opposite directions in the right and left by the amount corresponding to provided parallax information. Also, the body device 2 cuts out left and right two BG images from a planar source image having no parallax by itself with the two images shifted in the opposite directions in the left and right by the provided parallax amount and displays the cut out left and right BG images at the same positions in the left and right display systems. Furthermore, the body device 2 displays planar BG images having no parallax themselves in the left and right display systems while shifting them by an amount corresponding to the provided parallax information in the left and right opposite directions. This way, an OBJ image and a BG image are displayed with parallax provided by a novel method.

摘要： The 3-D image display consists of a pixellated display (11) that is illuminated through a beam splitter (16). A plan mirror (17) is provided on a movable mount (15) so that the mirror may be moved towards or away from an objective lens (12) positioned between the mirror (17) and the beam splitter (16). A quarter wave plate (18) is provided between the beam splitter (16) and the mirror (17) so that light reflected back from the mirror (17) through the quarter wave plate (18) passes straight through the beam splitter (16) to an eyepiece lens (13). Movement of the mirror (17) enables the mirror (17) to act as an optical path length modifier and permits an image from the display (11) to be presented at different focal positions. Rapid cycling through different focal positions results in the image being perceived as a 3-D image. As the objective lens (12) is positioned between the beam splitter (16) and the mirror (17), the objective lens (12) also acts as a demagnifying lens for images from the display (11). Preliminary demagnification of the image reduces the distances the mirror (17) is required to travel to provide the desired changes in focal position. This in turn reduces the demands on the performance of the mount (15), that are considerable in conventional systems where no demagnification is performed. In this way simple optical and mechanical components may be employed in the image display to generate perceived three dimensional images.

摘要： A 3-dimensional image is obtained from a 2-dimensional display by varying the apparent distance of the image from the viewer on a pixel by pixel basis. This can be done by positioning an array of pixel-level optical elements in alignment with the pixels in the image. In a preferred format, each of the optical elements is generally elongate and has a focal length which varies along its length with the result that the point along its length at which light enters the optical element determines the apparent visual distance of the associated pixel from the viewer. In the case of a cathode-ray tube application, controlling the position of entry of the light is done by controlling the electron beam to move a minute distance vertically as it scans horizontally. In a television application, the vertical distance may be determined by a depth component incorporated in the broadcast signal received by a television set. Applications and embodiments relating to computer monitors, film and still printed imagery are also described. Specifically there is provided a method of retrofitting 3-D information to conventional 2-D imaging, comprising the step of digitizing each scene, defining individual objects in the scene, assigning a specified depth to each object in the scene, scanning each pixel in the scene and assigning respective depth components to the pixels according to the specified depth.
摘要翻译：通过逐像素地改变来自观看者的图像的表观距离，从二维显示获得三维图像。这可以通过将像素级光学元件的阵列与图像中的像素对准来实现。在优选的格式中，每个光学元件通常是细长的并且具有沿着其长度变化的焦距，结果是沿着其进入光学元件的长度的点确定相关联的像素的视觉距离观众。在阴极射线管应用的情况下，通过控制电子束在水平扫描时垂直移动微小距离来控制光的入射位置。在电视应用中，垂直距离可以由并入由电视机接收的广播信号中的深度分量来确定。还描述了与计算机监视器，电影和静止打印图像有关的应用和实施例。具体地说，提供了一种将3-D信息改造成常规2-D成像的方法，包括对场景进行数字化，定义场景中的各个物体的步骤，为场景中的每个物体分配指定深度的步骤，扫描场景中的每个像素并根据指定的深度将各个深度分量分配给像素。

摘要： Three-dimensional imagery based on a series of two-dimensional images is produced and displayed. A frame (20) housing a series of image displays (22) displaced at differing radial distances from the center (39) of the frame is rotated at 60 hertz or greater. As each display rotates past the viewer, a different sectional slice of a three-dimensional image is displayed. Thus, a full rotation of the frame provides the viewer with a full view of the three-dimensional object. The high rotational speed of the system visually merges the slices and the radial displacement of the displays provides depth to the image. This combination results in the presentation of a true three-dimensional image without the need for viewing aids. Additionally, multiple viewers can view the same or differing three-dimensional images.

摘要： PCT No. PCT/NZ96/00028 Sec. 371 Date Feb. 2, 1998 Sec. 102(e) Date Feb. 2, 1998 PCT Filed Apr. 4, 1996 PCT Pub. No. WO96/31986 PCT Pub. Date Oct. 10, 1996The present invention relates to improvements in a three-dimensional display system. A transformation technique is described wherein deflection coordinates defining the spatial locations of the images written into the display volume are determined by transformation from a coordinate system based on the display volume to a coordinate system based on the one or more electron guns. The application further relates to a technique by which the location of an electron beam within the display volume may be determined. These techniques involve positioning conductive material at various locations such as the screen and the enclosure of the display itself so that the impinging electron beam may be detected and thy the location of the beam in the display volume may be derived. Image enhancing techniques are described in conjunction with the location techniques whereby conductive films are evaporated onto the screen and/or the enclosure. Modifications in voxel plotting techniques are described so as to enhance the quality of the image produced in the display volume. The technique includes interlacing the scanned print location. An additional improvement is provided by a particular conduction medium configuration superimposed or deposited onto the screen where the conducting medium incorporates information which is extracted or read from the medium by scanning a particle beam across its face so as to invoke momentary voltages or currents in the conducting medium.
